This guide details how to obtain and utilize the powerful Dark/Dragon-type Pokémon, Hydreigon, in Pokémon Scarlet and Violet. Hydreigon, a pseudo-legendary Pokémon, boasts impressive stats and is a valuable addition to any team. However, its evolutionary line (Deino and Zweilous) is exclusive to Pokémon Scarlet.
Acquiring Deino:
Deino and its evolution, Zweilous, are found in several locations within Pokémon Scarlet: Alfornada Cavern, Dalizapa Passage, Glaseado Mountain, Area Zero, and North Province (Area Two). Alfornada Cavern and Dalizapa Passage require Koraidon's high jump ability. Alternatively, Deino can be obtained from 3-star Tera Raids (post-3 gym badges), offering a chance for a Hidden Ability. Zweilous appears in 4-star Tera Raids. Hydreigon itself can be found in 5/6-star Tera Raids.
Obtaining Deino in Pokémon Violet:
Since Deino is Scarlet-exclusive, players of Pokémon Violet must obtain it through trading or Pokémon HOME. Trading requires a Nintendo Switch Online membership and utilizes the Union Circle. Pokémon HOME allows transfers from Pokémon Sword/Shield, Pokémon GO, and Pokémon Scarlet. The process involves moving Deino to the Basic Box in HOME, then transferring it to a PC Box in Pokémon Violet.
Evolving Deino:
Deino evolves into Zweilous at level 50, and Zweilous evolves into Hydreigon at level 64. Utilize auto-battling or Exp. Candies (especially L and XL) to expedite the leveling process.
Hydreigon's Strengths and Weaknesses:
Hydreigon's base stat total is 600, with high Special Attack and Attack, and good Speed. A Timid or Jolly Nature is recommended.
- Type Effectiveness:
- Super Effective Against: Dragon, Ghost, Psychic
- Weaknesses: Fairy (4x), Fighting, Bug, Dragon, Ice
- Resistances: Grass, Water, Fire, Electric, Ghost, Dark
- Immunities: Ground, Psychic
Hydreigon's 4x weakness to Fairy-type moves can be mitigated through Terastallizing. Its movepool allows for both physical and special attacking strategies. Flash Cannon (via TM) is a crucial Steel-type move to counter its Fairy weakness. Other recommended moves include Nasty Plot, Dragon Pulse (or Draco Meteor), and Dark Pulse.
| Stat | Base Stat |
|---|---|
| HP | 92 |
| Attack | 105 |
| Sp. Atk | 125 |
| Defense | 90 |
| Sp. Def | 90 |
| Speed | 98 |
| Total | 600 |
Hydreigon remains a potent Pokémon in Pokémon Scarlet and Violet, despite its vulnerability to Fairy-type attacks. Careful team building and strategic move selection will maximize its potential.
